Condemn by far. It's like a moving blender that sucks everything and destroys it. Stampede means u need to stop to cast and horses sometimes cant hit the target cause obstacles, waller affix, map layout, etc.

Monks can be hard because of Epiphany's teleport. U can go Tempest Rush or WoL. WoL may require a Tzo Krin's Gaze helmet to go ranged and avoid dsyncs from Epiphany. For T6 multiboxing, TR monks and Condemn Crusaders are really fast compared to other classes.
